Patent DE-2401040-A1 (DE)
Title: Swimming-pool counterflow current plant - has water outlet nozzle with cross-section of at least 70 square centimetres
IPC: A63B69/12
Filed: 1974-01-10
Abstract: In a plant designed to generate a counterflow in the water along the length of the swimming pool, the object is to produce a current of the same intensity as by other methods with reduced effort, and to give the current a more favourable cross-sectional form. The nozle cross-section may be 100 cm2 or more, and it may be rectangular, and wider than it is high. The width may be up to three times the height. The nozzle is pref. fastened to an axial centrifugal pump. Water enters the pump from the bottom, rising vertically upwards, and is discharged horizontally at the top of the pump unit.
Patent DE-2401263-A1 (DE)
Title: Cooling system for sec cooling zone in continuous casting - edges of slab shielded to retard their cooling rate
Inventor: GROTHE HORST
IPC: B22D11/124
Filed: 1974-01-11
Abstract: Cooling system for the sec. cooling zone of a continuous casting plant uses jets of water to cool the billet, the edges of the billet are cooled at a lower intensity than the remaining surfaces of the billet. The novelty is that the width of the jets or sprays impinging on the surfaces of the billet are controlled by adjustable screens or baffle plates located between the water nozzles and the billet or slab. The baffle plates are pref. located directly adjacent to the billet and if screens are used they are pref. positioned near the water nozzles. The baffle plates pref. consist of perforated plate mesh, or grid structures which are permeable to the water sprays. The system is used in continuous casting, of e.g. of steel slabs. The system ensures uniform cooling of the billet without premature solidification of the short edges of a slab which can result in cracks and fissures in the slab.

Title: Drive for longitudinal displacement of articles - has articulated lever with outer section rotated at twice drive shaft speed
Inventor: STARK FRIEDRICH
IPC: F16H35/00
Filed: 1974-01-17
Abstract: The ddrive thrusts the articles in a lengthwise direction, using a rotary drive shaft, and is intended particularly for their transport inside a vacuum chamber etc. An articulated lever comprising inner and outer sections is mounted on the drive shaft, its articulation point being halfway between the shaft and the point at which the force is exerted. At the articulation point a drive wheel is solidly secured to the outer link, and this wheel works in conjunction with another drive wheel on the shaft, so as to give a 1:2 speed increasing ratio. Typically a link chain can be used to transmit the drive between the wheels. The drive wheel on the shaft may be adjustable.

Title: Brush-holder for electric motor - has one or more coil springs acting directly on brush-head
Inventor: SCKERL WALTER
IPC: H01R39/38
Filed: 1974-01-22
Abstract: Brush-holder for electric motor has one or more coil-springs acting directly onto the brush head, the spring(s) being fixed to a U-shaped carrier whose first limb has a large-area positioning surface at the brush-holder body-piece's socket, the latter taking up the spring carrier itself. The carrier's other limb has, on the opposite-lying side of the socket, one or more small positioning surfaces whose site(s) is selected so that the liner of action of the opposition force(s) set up by the brush-holder passes through the larger support surface of the spring carrier's first limb and, thus, imparts to the carrier, in the brush-holder body-piece a non-tiltable position.

Title: Laser output wavelength meter - uses familiar energy measurement technique but with two beam splitters
Inventor: WERNER CHRISTIAN DIPL PHYS
IPC: G01J9/00
Filed: 1974-04-10
Abstract: A laser beam splitter reflects a part of the beam energy to a second beam splitter. Energy of a part of the beam behind the second splitter is measured by a monitor.

Title: Coil end tinning appts. - has coil receptacle over tin bath in form of hub with retaining mandrels with stepping rotary motion
Inventor: RUNIKS IMANTS
IPC: H01F41/10
Filed: 1974-06-05
Abstract: The automatic tinning apparatus is intended for the ends of coils which point outwards along the axis. The ends (15a) are soldered to tags on an insulated board or on a printed circuit board. The tinning is done by dipping in a tin bath (24). The coils (15) are mounted on radial mandrels (1), protruding around the circumference of a rotating hub (2) with stepping motion. The mandrels receive the coils from a magazine (4), and these are clamped in position by two jaws. The angular displacement of the hub proceeds in steps along the functional stations for loading, clamping, dipping and unloading positioned in a circle around the axis. The drive is transmitted through a gear system (11).

Title: Two-faced garden gnomes or ornamental figures - are provided with socket fitting for connection to any suitable article for secure fastening
Inventor: KEIDERLING GEORG
IPC: A01G9/28
Filed: 1974-07-26
Abstract: Garden gnomes, ornamental figures, etc. have two faces, one at the back and one at the front, which may be the same face or different faces, so that a face always shows when looked at from any direction. The figures also have at the base a socket connection which allows them to be attached to any ornamental object in a garden, e.g. an ash tray, stone, vase, etc. The socket ensures that the gnome is firmly fixed, and cannot blow away in a high wind. The provision of two faces is supposed to make the gnome or ornamental figure aesthetically more satisfying than such a figure with only one face.

Title: Central processor controlling switching network - has system to convert input signals from different sources into output signals
Inventor: ELYOVICS HERMANN
IPC: H04Q3/545
Filed: 1974-12-21
Abstract: It comprises a processor and a control unit which, when a call comes over an incoming line, stores in a register a code of a corresponding incoming trunk as a relative address. A further register receives a signal for the point of destination and the two codes determined the corresponding output signal. Storing of all input signals sets a program counting register in such a state, that it gives an address of a word writing command, which makes it possible consecutively to address code conversion tables kept in a store, in order to find a word containing a conditional route allocating code bit, which can be 0 or 1; in the first case the word belongs to a required outgoing route information contained in the route allocation code table.

Title: Non-fraying wash-resistant labels cut from thermoplastic strip - with blunt edged heated blade which forms thick fused edges
Inventor: SPARKS CHARLES E
IPC: B65C9/00
Filed: 1975-01-23
Abstract: A method of transversely cutting up a thin thermoplastics fibres strip, to form individual labels with non-fraying edges which are resistant to repeated washing, is as follows: a localised transverse band across the strip is continuously melted, so that the melted material penetrates right through the thickness of the strip and also permeates longitudinally on either side and is pressed into the interstices between the fibres; the material is then rapidly cooled and hardened on the face opposite to the application of pressure so that it bonds into the voids. Pref., a heated blade with a blunt edge and steeply inclined lateral surfaces is applied to one side of the strip, while a cold plate is used as an anvil on the opposite side. Sufficient material remains on either side of the inclined surfaces of the blade as it cuts through the heated portion to form thoroughly bonded anchorages which prevent fraying along the cut edges of the strip.
